Description

TECHNICAL FIELD

[0001] The utility model relates to a water tank and water purifier. BACKGROUND

[0002] At present, the water purifying equipment filters the impurities in tap water through the filter element to obtain purified water. Due to the limitation of the booster pump and the filter membrane, the general purified water flow is not very large. The mainstream water purifier currently has a water flow generally less than 2L / min. In order to provide better water experience for users, there is a kind of volumetric large flow water purifying product, which sets a water tank in the product, stores the purified water in the water tank, and realizes large flow water output through the large flow water pump. Generally, when the water tank is full of water, there is still a certain space between the liquid level and the top of the water tank, and the space is full of air. In order to make the water in the water tank flow out and be replenished, the air layer in the water tank is connected with the outside atmosphere. The existing germicidal lamp is usually arranged at the top of the water tank, and the light emitted by the germicidal lamp enters the water body after passing through the air. When the light passes through the boundary between the gas and the liquid, the intensity of the light is reduced due to the mirror reflection on the upper surface of the liquid, resulting in poor sterilization effect of the germicidal lamp.
